It’s 1980-something in small town America, and life seems just perfect. Kids hang out at the video arcade; dads mow their white picket-fenced lawns; and the town sheriff regularly stops by the local diner for a slice of cherry pie and coffee strong enough to chew.
But it’s not just teen diaries that hide secrets in Pleasanceville. What’s happening in the high-security government research lab in the woods? Who is the corrupt mayor covering for? And can our intrepid band of misfits save the town in time to get to prom?
The Goonies meets Twin Peaks meets Stranger Things in this totally tubular adventure! Now in its interdimensional 16th year, the London 50-Hour Improvathon is the ultimate ‘you had to be there’ event.
What is this?
It’s a 50-hour improvised comedy soap opera in 25 hilarious episodes – catch just one standalone episode, or binge-watch the whole season like your favourite Netflix show.
Starting at 7pm on Friday and playing continuously in 2-hour episodes until 9pm on Sunday (yes, right through the nights!) with a live band and refreshments available throughout.
Featuring stars of Olivier Award-winning Showstopper! The Improvised Musical and Tony Award-winning Mischief (The Play That Goes Wrong), alongside comedians, performers, up-and-comers and international guests throughout the weekend. Stay tuned for the full line-up, to be announced in 2026.
This spring at the Pleasance Theatre, London, join the freakazoids for an upside-down adventure like no other. Sleep? Where we’re going, we don’t need sleep.

For anyone who would benefit from a more chilled out atmosphere to enjoy this year’s bodacious adventure.
